DRAIN-TILE.

Specification of Letters Patent.

Patented Mar. 2'?, ilhtt.

Application filled August 17, 1915. serial Ito. 45,897.

To all whom it may concern Be it known that We, BENJAMIN H. Rani), UILMSTED A. Reno, and ALBERTO N. REED, citizens of the United States, residing at Hightstown, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Drain- Iiles, of which th following is a -specification.

This invention relates to drain tiles, and one object is to provide atile of increased stren h, stability and carrying capacity.

Anot er object is to provide a main tileso.

constructed'that branch tiles can discharge Water thereinto' in a more efiicient manner section which may be employed at pointswhere branch drains connect with the main drain;

Fig. 3 is an end view of a main drain tile with two branch tiles communicating therewith, parts being in section;

Fig. 4 is a plan view of the tile system shown in Fig. 3; and,

Fig. 5 is a longitudinal vertical section through a system of tiles such as shown in Figs. 3 and 4:.

Referringto the drawings in detail, the standard tile section is designated bythe reference character A, and the special section, used for branch connections, by the reference character B.

The tile section A has a flat bottom 1, and

'side walls 2 extending upwardly therefrom at substantial right angles thereto. The top of the tile is semi-cylindrical in shape so "as to form an arch 3. Below the arch is a horizontal brace wall or partition 4-, rigidly uniting the side walls and dividing the tile into an upper compartment, segmental -1n cross section, and a lower compartment substantially rectangular in cross section. The side walls are preferably provided with a series of small openings 5 through which water may seep into the drain. It will be noted that the tile .has its maximum ,width at the bottom so that its carrying capacity is relatively .as great when the water is shallow, as when the tile is nearly full. In this respect the improved tile shown herein is different from the round or sole tiles heretofore employed, in which latter tiles the maximum carrying capacity. is not reached until the tile is approximately half full of Water. 1

A special tile section, employed for branch tile connections isshown in Fig. 2,

and is identical with the tile shown in Fig. 1

except that it is provided, adjacent one end with. a notch 6, adapted to receive the end of a branch drain It will be noted that this notch is formed just above the partition wall 4. It may be readily cut out pf the tile when the latter is in a soft condition.

In some cases, where desirable, a hole may be cut in a tile section, by means of a. cold chisel, or otherwise, wherever it is necessary to connect wlth a branch dram, but such holes should always be cut above the parti-.

tion wall.

In Figs. 3, 4, and 5, are shown main and branch tiles connected in the manner above described and assembled in the relation which they might well occupy in actual use. The branch tiles 7 are relatively small and preferably circular in cross section.

As clearly shown in Fig. 5, these branch tiles discharge their water into the upper or segmental chamber of the main tile, at a point above the partition wall, and such water flows along on the partition wall, gradually discharging downwardly into the lower chamber through the more or less open joints 8, between the ends of the tile sections. In this way, the discharge of water from the branch tiles is not interaccumulated in the lower compartments of the main tile. Where branch tiles are connected, as heretofore, to a main tile on the same level, the fiowage of Water therethrough is often impaired by reason of water which may have accumulated in the main tile. By use of the present invention, difficulties of this kind can be avoided, and free flow frgm the branch drains at all times insured.

Moreover, the upper or segmental compartment acts in the nature of an air chamber through which fresh air may flow and displace the sluggish air, saturated with moisture, which occupies the lower compartfered with by any water which may have ment, incontact with the water. Such fresh air being not so saturated, andv probably of a difl'erent tem rature and density, tends to cause a circu ation through the compartments and joints of the tile, and thus prevents stagnation.

earth. The flat bottom of the tile, in addi tion to affording a maximum carrying capacity at low water levels, makes it easy to place and retain the tile sections in position while they are being laid,

i What we claim is:

A drain tile'sys'tem comprising a maindrain having a flat bottom, an arched top,

side walls, and a horizontal partition wall extending between said side walls parallel with said bottom and dividing the tile into an upper compartment, segmental in cross sectionyand a'lower compartment substantially rectangular in cross section, in combination with branch drains tapping the upper compartment of said main drain above the partition wall thereof, said main drain being composed of sections having comparatively open joints between them, wherebywater discharged into the said upper compartment from said sidedrains can escape downwardly through such joints into the lower compartment. 4

In testimony whereof we have afiixed our signatures.
